To get you into the holiday spirit a special Swedish-style musical event is held in Paris. The event is always held at the Swedish Church (Svenska kyrkan) and most years at a large church in Paris; Paroisse de la Madeleine, Notre-Dame de Paris. The event is a musical Swedish tradition celebrating lightness during the winter darkness.
